I grew up in Pocatello and my Dad still lives there and one of my sons has been there for a couple of years now attending ISU. My brother is an ER physician in Rapid City SD (he is a hunting nut and not so much into fishing these day) and he has a very dim view of the medical profession in Pocatello. Idaho Falls is slightly better but for good care you would be going to Salt Lake which is about 150 miles south. You won't be able to get to the West Entrance of Yellowstone National Park in an hour unless you are into low altitude flight (figure closer to 3). If you are looking for good restaurants or culture Pocatello is not a place to look. ISU really does not add much. (I am an ISU graduate) Winter in Pocatello would be similar to Spokane for the amount of snow, but likely colder. Pocatello will be 5-10 degrees warmer than IF and 10-15 degrees warmer than the upper Snake River Valley on some days.
